Re: (IAAC) Condensation on the primary was Creating a detailed deep-sky log... (LONG)



Hi Nick, I am sure you are correct, I have to stand my scope up vertically
when I finish a session, (not much room!) and there are definately faint
deposits on the Mirror from the condensation that results, I have had to
clean it twice in 1 year which cannot be good for it, though I took great
care when doing so, I did read recently though that the scope ought to be
stored on it's side, and with the cap off, to allow some air circulation
which can largely overcome such difficulties, so I will be constructing a
rack (rather like an oversize gun rack) for my 8" newtonian, I imagine
however that larger instruments must present a more difficult problem,
especially if space is an issue. (no pun intended!!)
